One (colour) is the British way of spelling, the other the American way (color) but the others are definitely wrong. As non-native speaker I mix up British and American spellings permanently, must look odd.

This cracks me up! I'm American and I was really confused at first too. It was funny. At first I thought is was a typo. Oops!

Example: behavior and behaviour
(Even right there I was attempting to write the British spelling first and the American one came out...how funny!)

Harry Potter (well, J. K. Rowling) has definately helped me with my English (in terms of grammar, punctuation and all). I write much more fluent nowadays. I'm finishing my last year of secondary school, and with that comes lots and lots of writing.

Immensely! I use words that I normally wouldn't have if I hadn't read the Harry Potter books. Jk Rowling used such elegance and intellect when penning her books that there's really no way you don't gain some sort of knowledge from it, be it vocabulary or an extended imagination.

Harry Potter hasnt really helped my Grammar. Because grammar is one of those things that I don't reallly care about. as you can already tell. but when I try and want to use proper english and stuff like that. I guess you can say it sorda has.... idk.

ehm... actually not...
i love reading and because of that i read many books and they all together have improved my grammar (i think and HOPE)
i read them in german and german grammar is very difficult compared to english (its also hard to learn!) so reading many books is always advisable and improves your grammar
